Regarding the mechanism.

条件で維持される。Liquids, such as contact lens cleaning fluids, are typically stored in squeezable bottles that allow the user to manually and repeatedly dispense the storage fluids, which liquids may become contaminated by microorganisms such as bacteria. Therefore, expensive bactericides are sometimes prescribed in the liquid, for example, salt-containing formulations of contact lens washes. Further, the squeezable dispensing bottle is sometimes provided with a nozzle having a filtration membrane, and the filtration membrane is capable of permeating the dispensing liquid and changing the dispensing liquid. The air drawn in through the nozzle is therefore also permeable. The permeable membranes also impermeable to bacteria in order to protect the inhalation from bacteria carried in contact with the reservoir solution, so that the solution remains sterile.

壁の次の絞り出しもまた妨げられる。However, since a filter membrane material having sufficient hydrophilicity allows the permeation of an aqueous salt solution, salt content is often retained on the filter membrane, which increases resistance to the passage of intake air and results in partial obstruction of intake air flow. Not only does the smooth expansion of the bottle wall be hindered, but the subsequent squeezing of the bottle wall is also hindered when a large amount of solution needs to be dispensed.

〔課題を解決するための手段〕[Means for Solving the Problems]

この発明に関するノズル機構は、とりわけ、コンタクト
レンズ用溶液の反復分与において、絞り出しにより液体
を分与するびんに吸気手段を設ける。The nozzle mechanism according to the present invention is provided with suction means for a bottle that dispenses liquid by squeezing, especially in the repeated dispensing of a solution for contact lenses.

を通って液体が流れ、前記液体管から排出される。In a specific embodiment, the nozzle mechanism includes a molded elastomeric diaphragm having a strainable valve blank in the liquid conduit, the valve blank leaking liquid from the container recess. To prevent this, the one-way valve is normally closed and the valve is opened by passing pressure through the opened valve by causing strain in the pressure of the liquid loaded on the diaphragm due to the loading of pressure into the container. Liquid flows and is discharged from the liquid pipe.

部は疎水性を有するので、貯蔵液体の透過が妨げられ、
従って、その濾過材から吸気管への吸気流れを容易にす
る。The embodiment of the nozzle mechanism also has a filtering part, which is hydrophobic so that the permeation of the stored liquid is impeded,
Therefore, the intake flow from the filter medium to the intake pipe is facilitated.

その濾過部は、空気を濾過するが、バクテリヤを透過し
ない。従って、容器内の貯蔵液体にバクテリヤが混入し
ない。The filter section filters air but does not allow bacteria to pass through. Therefore, the stored liquid in the container is not contaminated with bacteria.

円滑に行われ液体分与が連続して確保される。The nozzle mechanism according to the present invention has two transparent diaphragm means.
And the first diaphragm portion is provided in the liquid pipe means, while the second diaphragm portion is provided in the intake pipe means,
Since the two parts are separated, the second diaphragm portion is not interfered with by the solution to be dispensed, so that the intake flow is smoothly performed each time the solution is squeezed out and the liquid is continuously dispensed.

液体管手段内に設けた第１ダイヤフラム部を弾力的にひ
ずむ一方向弁構造としたので、一旦、排出された汚染の
おそれのある液体が容器内に逆流しない。The one-way valve structure in which the first diaphragm portion provided in the liquid pipe means is elastically distorted does not cause the once discharged liquid that may be contaminated to flow back into the container.

吸気管手段内に設けた第２ダイヤフラム部にバクテリヤ
不透過の性能を有せしめたので、容器内の液体が吸気に
よって汚染されない。Since the second diaphragm portion provided in the intake pipe means has the property of impermeable to bacteria, the liquid in the container is not contaminated by the intake air.

与以前に流出される。The tube-shaped valve portion 24dd extends downwardly and ends at the face around the teat 18j against the adapter wall 18e, under compression by the boss 20f, with a tapered sealing ring 25 where it is normally sealed, whereby the container is closed. Leakage of stored liquid (salt water) is prevented under hydrostatic pressure when inverted by hand, and any backflow of contaminated air or liquid from the interstitial space A in the neck 16 of the bottle is also prevented. The back-flowing liquid is additionally impeded by the projection of the conical teat 18j in the tubular nozzle portion 24d to minimize the volume of liquid that remains in the tubular portion 24d when the dispensing flow is stopped. A small amount of residual liquid in the tubular portion 24d, where air contamination can spread, is drained before the next dispense.

液体管の経路は次の通りである。The path of the liquid pipe is as follows.

When the salt water container is squeezed out of the nozzle mechanism 12 and the nozzle mechanism 10, the liquid flows through the two passage holes 30, 30 and exerts a necessary inlet water pressure on the diaphragm portion 24e of the diaphragm 24, The diaphragm portion 24e elastically distorts to further compress the tubular valve portion 24dd against the boss 20f. This alters the additional compression of the valve portion 24dd and separates the seal ring 25 from the wall 18e, which
Liquid flows through the annular interstitial space A, which is enlarged by the strain of the diaphragm. The liquid flow through the interstitial space A, as indicated by the arrow B, leads the liquid through the tubular nozzle 24d for discharge.

動する。Thus, when the flexible wall 14 is squeezed out, the seal ring 25 acts as a one-way valve allowing only the outflow of the dispensed liquid, so once the manual squeeze is returned,
The additional compression of the valve portion 24dd loosens and the remaining compression of the valve portion 24dd causes the seal ring 25 to rest and then close tightly against the wall 18e to close the one way valve. Thus, if the dispenser is exposed to contaminated liquid, such as by dripping into the contaminated liquid, any backflow of liquid or air is impeded. Thus, the valve portion 24dd acts on the seal ring 25 as an elastomeric bias spring.

Hole 131 formed through hole 118aa
Flowing through. In the arrangement of the second embodiment, the suction air does not come into contact with the sterile liquid L in the sealed bag 119, and therefore the liquid flow path and the air suction flow path are completely separated and need to be sterile. It is possible to eliminate any passage of the intake air which is not present.

The filter medium is fitted and supported at the inner circumference by the diaphragm valve portion 224dd and at the outer circumference by the thick portion 224b, so that the annular intermediate member is exposed to form the air filtering portion 224a. Due to the additional structural lamination, the filter media can be embedded within the radial protrusions 224c of the elastomeric material. The filtration membrane material of the filtration unit 224a is hydrophobic because it prevents passage of the sterile liquid L (salt water), and also does not pass bacteria, but since it passes air, the suction air is, as will be described later,
During inhalation, the sterile liquid is filtered, preventing bacteria from entering so that it is not contaminated. A suitably air-permeable hydrophobic filter material, for example, is approximately 0.45 impermeable to bacteria.

Ends with a tapered sealing ring 225, which is normally sealed under compression by, which prevents leakage of the stored liquid L under hydrostatic pressure when the container is manually inverted.
Any backflow of contaminated air or liquid from the interstitial space A within the bottle neck 216 is also impeded. The countercurrent liquid is conical nipple 21 within tubular nozzle portion 224d in order to minimize the volume of liquid remaining in tubular portion 224 when dispensing flow is stopped.

は、非液体側上に設けられる。In FIGS. 10 and 13B, when flexible wall 214 is squeezed to dispense liquid L from inverted container 212 and nozzle mechanism 210, the liquid becomes diaphragm 224.
The required inlet water pressure is exerted on the liquid impermeable filter portion 224a of FIG. 1 and its diaphragm 224 is elastically distorted to further compress the tubular valve portion 224dd against the boss 220f. This alters the additional compression of the valve portion 224dd and transfers the annular seal ring 225 onto the face of the adapter 218 to allow liquid to flow between the two in the adjacent portion of the annular interstitial space A. . The annular gap space A is expanded by diaphragm strain. The cap 220 has a narrow perforated groove 220i, as shown in FIG. 10, which groove is above the diaphragm 224 to allow air movement due to strain of the diaphragm 224, or on a non-dry side. Provided on the liquid side.

りばねとして作動する。The liquid flow through the interstitial space A directs the liquid through the tubular nozzle 224d for discharge, as indicated by arrow B. The elastomeric valve portion 224dd and the seal ring 225 make the flexible container wall 21
When 4 is squeezed out, it acts as a one-way valve allowing only the outflow of dispensed liquid. The additional compression of the valve portion 224dd once loosens when the hand squeeze is returned and the remaining compression of the valve portion 224dd causes the seal ring 225 to re-install and tightly seal against the wall of the adapter 218. The one-way valve is closed and any backflow of liquid or air is blocked. Such backflow could, for example, be due to the dispenser dripping into the contaminated liquid.
It occurs if exposed to contaminated liquids. Thus, the columnar valve portion 224dd acts as an elastomeric bias spring on the seal ring 225.

空気管の経路は次の通りである。The path of the air tube is as follows.

る。In Figure 13A, a flexible squeezable container wall 2
Ambient air is drawn into the inlet passage 230 and directed downwards above the passage hole 228 to draw in the 14 re-expanding air and to restore the dispensed liquid. The air that has been filtered through the filtering portion 224a flows through the adapter skirt 218 and the container neck 216. Thus, the filtering portion 224a of the diaphragm 224 serves both as a suction air filter and as a water distorted portion of the diaphragm in the liquid tube. Thus, a water distortable air filter in a diaphragm structure, among other things, can simplify the air tube and nozzle mechanism without dangerous contamination of sterile liquid during storage and continuous dispensing. .

ものである。Although the specific embodiments of the present invention have been described in detail, in the case where various changes and modifications of the present invention are merely changes in design or the like without departing from the spirit of the present invention, it will be obvious to those skilled in the art. It is intended that the scope of the invention should not be limited by the foregoing examples, but the scope of the appended claims is to cover any modifications within the true spirit and scope of the invention.

〔発明の効果〕〔The invention's effect〕

従来のこの種のノズル機構は、単一の濾過膜素材で吸気
と液体の双方を透過する構造であり、かつ、親水性を有
していたので、例えば、分与液体に塩水溶液を使用する
と、前記濾過膜面に塩水が付着残留し、それが吸気の吸
込みを妨げ、結果的に液体の排出に円滑を欠いた。A conventional nozzle mechanism of this type has a structure in which both a suction air and a liquid are permeated by a single filtration membrane material and has hydrophilicity. Therefore, for example, when a salt solution is used as a dispensing liquid, The salt water adhered and remained on the surface of the filtration membrane, which hindered the intake of intake air, resulting in a lack of smooth liquid discharge.

これに対して、本発明によるノズル機構は、透過ダイヤ

る。On the other hand, in the nozzle mechanism according to the present invention, the permeation diaphragm means is divided into two parts, liquid and intake, and is distinctly provided, so that the diaphragm of the intake system is not affected by the dispensed liquid at all. Since the intake air is always sucked in reliably and sufficiently, the liquid is discharged smoothly and reliably all the time.

液体管手段内に設けた第１ダイヤフラム部を弾力的にひ
ずみ可能な一方向弁にしたので、一旦排出された液体が
容器内に逆流するおそれがないから、容器内の液体が汚
染されない。Since the first diaphragm portion provided in the liquid pipe means is a one-way valve that can be elastically deformed, there is no possibility that the once discharged liquid will flow back into the container, so that the liquid in the container is not contaminated.

更に、吸気管手段内に設けた第２ダイヤフラム部にバク
テリヤ不透過の性能を有せしめたので、容器内の液体
は、吸気によっても汚染されず、極めて高度の衛生管理
が徹底して達成され得るようになった。Further, since the second diaphragm portion provided in the intake pipe means is made impermeable to bacteria, the liquid in the container is not contaminated by intake air, and extremely high hygiene control can be thoroughly achieved. It became so.
